Steel connection design software

3D/BIM input and FEM solver for the design and analysis of steel connections in real time of any node type

The input of NeXus is revolutionary!

Select node elements from a library of parametric objects, model the connection in 3D rotating it and modifying all components in real-time, resulting in an extraordinary design speed and control.

The input environment in NeXus is completely 3D. Design any type of connection in a much more streamlined and rapid method than other software with numerical input editors and three-dimensional views without any interaction.

Thanks to parametric three-dimensional modelling, you can easily achieve unions with a large number of rods and quickly indicate loads in multiple directions.

You have real-time stresses, deformations, strength reserves of the individual components and an immediate visualisation of the node behaviour with its safety margins.

With NeXus you can quickly tackle detailed design and connection analysis:

• steel column beam node;
• beam-to-beam connections;
• steel beam-column union;
• upwind ends;
• complex multi-member connections;
• steel-concrete*;
• connections included in Eurocodes (EC) specifications.

Input, meshing and results are dynamic and give the designer an extraordinary awareness and ability to manage design and calculation.

A few steps to obtain consistent calculation and verification results of steel nodes with tension maps, printouts, reports and working drawings

Thanks to the powerful graphics and calculation engine integrated in NeXus, modelling and calculation of any connection is very simple and fast, with automatic generation of the FEM model of the connection.

• Various components are identified in the union: connected beams, plates, bolts, welds, etc;
• All components of the union, within the framework of the FEM method, are appropriately schematised: connected beams and plates as shell elements, bolts discretized with finite elements and connected with links to the plates, welds modelled as a set of elements capable of transmitting and receiving parallel and orthogonal σ and τ;
• The union analysis, employing either linear or non-linear calculations, yields the stress and deformation profiles of the various components;
• Through the integrated FEM solver, various analyses are derived, including node stiffness analysis, fatigue analysis, and node capacity design specifically tailored for seismic zones^*;
• Buckling calculations promptly identify local buckling within the rods and determine critical load factors*;
• Each component undergoes verification utilizing standard formulas (Eurocode, EC), with the FEM model's point response automatically interpreted to assess stresses directly comparable to material strengths;
• Verifications encompass tensional and/or deformational assessments, incorporating diverse failure criteria when a normative verification is unfeasible.

From the analysis, we obtain clear information on the behaviour of the union/connection.

The results are tension maps that are able to represent all stress and test conditions at a glance.
